Technical field
The present invention relates to the provision for disengagement of a kind of diesel engine main shaft and bearing.
Background technology
When two bearings of the main shaft on the cooling water pump of diesel engine need to change after damage, need specialized work to dismantle bearing and axle sleeve protect main shaft injury-free, then again press-fit, and if use manpower is directly dismantled and easily damaged main shaft.
A kind of diesel pump main shaft bearing assembly and disassembly platform is disclosed in prior art, it comprises base, oil pump, stud, cover plate, Bearing housing, block, bearing pressure tear head and main shaft open, oil pump and stud are fixed on base, oil pump top is arranged with bearing pressure and tears head open, cover plate is fixedly connected with stud, block is placed in cover plate, and main shaft top is placed in Bearing housing, and tail end is placed in bearing pressure and tears open in head.When adopting above-mentioned disassembly table to dismantle bearing, first take off the block on cover plate and Bearing housing.The bearing one end will dismantled by main shaft is downward, and bearing is through the macropore of hardy hole, and axle body is moved to aperture portion, and axle head drops on bearing pressure and tears open in head, puts block and prevents main shaft from sliding or toppling over.Start oil pump, its expansion link rising jack-up bearing pressure tears head i.e. jack-up main shaft open, and the bearing that will dismantle is blocked by cover plate 4, along with oil pump expansion link extends, bearing and main shaft are thrown off, and block, main shaft, bearing are taken off successively, then dismantle axle sleeve and the bearing of the other end.There is following problem in above-mentioned disassembly table:
The first, base is connected by stud with cover plate, and in the process of dismounting, the top power effect applied due to oil cylinder is large, is easy to cause the screw thread on stud damaged.
Second, the matching relationship of dismounting fore bearing and main shaft is interference fit, by the effect of oil cylinder and block, bearing is dismantled during dismounting, this mode is pressure dismounting mode, although distinguish to some extent with the mode of manually knocking dismounting, but still damage can be caused to the axle of interference fit and bearing surface.
Summary of the invention
For the deficiencies in the prior art, the invention provides the provision for disengagement of a kind of diesel engine main shaft and bearing, the present invention can not cause damage to the axle of dismounting and bearing.
The technical scheme solved the problems of the technologies described above is as follows:
The provision for disengagement of diesel engine main shaft and bearing, it comprises base, oil pump, bearing pressure tear head open, after the middle part of described base arranges an installing hole, this base is Back Word type, described oil pump is arranged in the installing hole on base and is fastened as a whole with base, the end of the piston rod of oil pump is torn head open with bearing pressure and is fixedly connected with, and the upper end of described base is provided with a hardy hole be communicated with installing hole;
Also comprise the first cylinder, the second cylinder, the first line-frequency induction heat block, the second line-frequency induction heat block, first cylinder and the second cylinder are all arranged in described installing hole, and on the first cylinder side wall surface relative with a pair that the second cylinder symmetrically is anchored on base, first line-frequency induction heat block is fixedly connected with the piston rod of the first cylinder, and the second line-frequency induction heat block is fixedly connected with the piston rod of the second cylinder.
Have employed such scheme, after the middle part of described base arranges an installing hole, this base is Back Word type, the base of this shape in use, when oil cylinder imposes top power upwards to axle, when base also can be subject to this top power, owing to base there is no the connection of bolt, but an entirety, therefore, base can not be damaged.On the side wall surface that first cylinder is relative with a pair that the second cylinder symmetrically is anchored on base, the first line-frequency induction heat block is fixedly connected with the piston rod of the first cylinder, and the second line-frequency induction heat block is fixedly connected with the piston rod of the second cylinder.Stretch out drive first line-frequency induction heat block by the first cylinder and move to bearing, by the first line-frequency induction heat block, bearing is heated, equally, stretch out drive second line-frequency induction heat block by the second cylinder and move to bearing, by the second line-frequency induction heat block, bearing is heated, bearing is after acquisition heating, according to the principle of expanding with heat and contract with cold, interference fit relation between bearing and axle is little by little by tightly fluffing, thus under the active force of oil pump, bearing axle can be departed from, the surface of bearing and bearing can not be damaged like this.
Described first line-frequency induction heat block and the second line-frequency induction heat block all curved.The line-frequency induction heat block of arc can coordinate well with bearing, thus improves the efficiency of heating surface.
Also comprise heating controller, this heating controller comprises touch-screen, PLC, driver and relay, the output of touch-screen is electrically connected with the input of PLC, the output of PLC is electrically connected with the input of driver, the output of driver is electrically connected with the coil of relay, first normally open contact of relay is electrically connected with the first line-frequency induction heat block, and the second normally open contact of relay is electrically connected with the second line-frequency induction heat block.By the control of heating controller, fast and effeciently can heat, and heating parameters can be set according to the parameter of bearing, effectively to improve the efficiency of heating surface.
